+**Question 1:** The parameter cutoffValue is part of the constructor method PigGame.
+
+**Question 2:** 0.0
+
+**Question 3:** In method playTurn, 
+
+    while(!rolledOne && score < cutoff && score + s.getScore() < 100)
+    {
+      d.roll();
+      if (d.getUpValue() == 1)
+      {
+        score = 0;
+        rolledOne = true;
+        numBusts += 1;
+      }
+      else
+        score = score + d.getUpValue();
+    }
+
+    return score;
+  }
+}
+
+**Question 4:** I think the problem(s) might be located in either PigGame or ScoreSheet. I think it is unlikely that the issue is with Die or Main.
+
+**Question 5:** The problem was in the file Die.java, with the method roll, value upValue. The program was casting random numbers between 0 and 1 into int values, which is always 0, then adding 1 which leaves us with 1 as the upValue every time. I moved the cast outside of the parentheses so that the random value is multiplied by 6 before it is cast into an int and added to 1. 
+
+**Question 6:**
+
+10: 14
+
+15: 13
+
+20: 12
+
+25: 12
